1 Be it known that I, HEINRICH GERDES, a subject of the German Emperor, residing at Berlin, in the Empireof Germany, have invented certain new and useful Im rovementsin Processes of Producing Gas, which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to the manufacture of gas by what is commonly known as the suction process, and in which mixed air andva or is drawn through an incandescent mass 0 fuel.

More particularly the invention relates to that class of producers inwhich bituminous bustible matter is employed.

Heretofore in the'manufacture of gas: by the above process from bituminous coals it has been customary to coke thel'coal within the producer, distilling off-the gases therefuel or other fuel containing volatile come from and then'redirecting these distilled gases into the-lower end of'the mass of burn ing coke.. The bbject of this treatment is to burn all of the distilled ase's, converting the same into carbon dioxi and'va or of water, i and then'to decompose these pro ucts, so as to form carbon monoxid and hydrogen. It has been found however, in the practical operation of producers ofthis ty e that a considerable percentage of the diet led gases will 7 through the lncandescent fuel unconsumed and without decomposition, with the result that the final resulting gas is not of uniform quality andwomposition.

It is the objectof the present process to avoid this objectionable result, and the invention broadly consists in a rocess in which j the distilled gases are burns in an excess of oxygen and in advance of their passage through the incandescent fuel.
